<p>The primary goal of a non-inferiority trial is to demonstrate that the new intervention is not worse than the standard by a predefined margin. This differs from a superiority trial, which aims to show that the new intervention is better than the control, without specifying a margin of non-inferiority.</p> Signup and view all the answers

<p>A new intervention may be of interest in non-inferiority trials because it is less toxic, less invasive, less costly, requires fewer doses, improves quality of life, or provides other value to patients, even if it does not demonstrate superiority over existing therapies.</p> Signup and view all the answers

<p>The key objective of studies of equivalency is to test whether a new intervention is equivalent to an established one, while the objective of studies of non-inferiority is to test whether the new intervention is no worse than, or at least as good as, some established intervention.</p> Signup and view all the answers

<p>Demonstrating non-inferiority in a clinical trial is significant because it provides evidence that the new intervention is at least as good as the standard treatment, which can be valuable in cases where the new intervention offers other benefits such as reduced toxicity, invasiveness, or cost.</p> Signup and view all the answers
